Abstract

This research aims to identify strategies for developing construction materials based on plastic waste to address environmental issues and support sustainable construction. The urgency of this research is based on the increasing volume of waste at the Sumompo landfill in Manado City, which reaches around 330 tonnes per day, as well as challenges in implementing construction materials made from plastic waste. Waste management in Manado faces complex and interrelated problems. Previous research has shown the technical potential of waste polymer bricks and concrete, but it is still constrained by industrial readiness, regulations, and public acceptance. The integration of these issues points to the urgency of research into the development of applicable plastic waste-based construction materials. Therefore, this study focuses on the utilisation of plastic waste as a construction material to reduce environmental impact and improve the sustainability of the construction sector. The analysis approach in the existing waste management system at the Sumompo landfill site, Evaluation of Plastic Waste Management and Utilisation using a SWOT-AHP-based strategy approach. SWOT analysis is used to identify internal factors (strengths and weaknesses) and external factors (opportunities and threats). Subsequently, AHP is used to prioritise implementation strategies, with the findings of the analysis showing that a multi-sector approach is needed to optimise the use of plastic waste as a construction material, taking into account industry readiness, regulations, and public acceptance as key factors for successful implementation. These findings provide strategic recommendations for the development of environmentally friendly construction materials. The results of the weighting of the strategic goals of technological feasibility, environmental impact, and policy and regulatory framework development are still high.Keywords: Sustainable Construction Materials, Plastic Waste, SWOT-AHP Analysis

Abstract

The degradation of irrigation water quality presents a critical challenge for sustainable agriculture, particularly under increasing hydrometeorological pressure. This study developed an Internet of Things (IoT)–based monitoring system and applied the Canadian Council of Ministers of the Environment Water Quality Index (CCME WQI) to evaluate temporal variations in irrigation water quality.The system integrates pH, water temperature, total dissolved solids (TDS), and turbidity sensors with an ESP32 microcontroller, enabling real-time data transmission to a cloud-based platform. Water quality assessment was conducted from August to December using CCME WQI, with objectives defined based on national regulations and internationally recognized guidelines.The results reveal a progressive decline in irrigation water quality throughout the monitoring period. CCME WQI values decreased from 70.24 (Fair) in August to 32.28 (Poor) in December, indicating increasing frequency and severity of guideline exceedances. Turbidity was identified as the dominant contributor to water quality degradation, particularly during rainfall events, followed by episodic pH reductions and diurnal temperature variability. In contrast, TDS remained stable and consistently below threshold values.The integration of high-resolution IoT monitoring with the CCME WQI framework provides a reliable and objective approach for continuous irrigation water quality assessment. This method effectively captures temporal dynamics and supports early identification of critical degradation periods, offering a practical basis for adaptive irrigation water management.
